Maxim Mironjuk - February 12, 2025

A long form that gets lost when a tab is accidentally closed costs users time and nerves. An autosave pattern in Alpine.js automatically saves the draft to localStorage, with debounce, a visible save status, and clean conflict detection across multiple open tabs.

Sticky Add to Cart Bar on Scroll with Alpine.js

Maxim Mironjuk - February 11, 2025

Once the customer scrolls past the original add-to-cart button, a lean sticky add to cart bar takes over at the bottom of the screen. With x-intersect instead of a custom scroll listener, this pattern can be implemented performantly and without layout thrashing, in sync with variant selection and quantity in the main form.

Keyboard-Accessible Dropdown with Alpine.js

Maxim Mironjuk - February 07, 2025

A dropdown that only works with a mouse is useless to keyboard users and screen reader users. The WAI-ARIA listbox pattern defines precisely how arrow keys, Home, End, Escape, and type-ahead must behave in a dropdown, and Alpine.js makes the implementation surprisingly elegant.

Maxim Mironjuk - February 03, 2025

The init() hook shows up in every Alpine.js tutorial, but destroy() is frequently overlooked. That is exactly what causes slow-building memory leaks, orphaned event listeners and bugs that only surface after several page navigations. This article explains both hooks in full.

Unsaved Changes Warning with Alpine.js

Maxim Mironjuk - February 02, 2025

A user who invested twenty minutes in a form and then accidentally closes the tab loses their entire work if no unsaved changes warning kicks in.

Scroll Progress Bar on the Page Edge with Alpine.js

Maxim Mironjuk - January 16, 2025

A scroll progress bar shows readers of a long article at a glance how much content still follows and how far they have already come. With Alpine.js, this progress indicator can be built in a few lines, bound performantly to the scroll event, and shown either as a horizontal bar at the top or vertically on the page edge.

Alpine.js Hydration Mismatches with Server-Rendered Content

Maxim Mironjuk - January 14, 2025

Alpine.js hydration mismatches happen when the state of an x-data object on first render does not match what the server already delivered as HTML. Unlike React or Vue, there is no virtual DOM reconciliation that logs the difference automatically. Instead, the bug shows up as visible flashing, wrong form values, or content that briefly appears and then vanishes again.

URL-Based Tab System Without a Router in Alpine.js

Maxim Mironjuk - January 11, 2025

Tabs that show the same panel again after a reload, support the browser's back button and can be shared as a deep link by email are not SPA features. They are URL hygiene, achieved with ten lines of Alpine.js and the browser's native History API.
